Understanding deconfined quantum critical points from crystalline categorical Landau paradigm
Hiromi Ebisu, Bo Han, Weiguang Cao
Deconfined quantum critical points (DQCPs) involving lattice symmetries evade the conventional Landau paradigm because the competing orders break incompatible internal and crystall…
Learning transitions of topological surface codes
Finn Eckstein, Bo Han, Simon Trebst +1
For the surface code, topological quantum order allows one to encode logical quantum information in a robust, long-range entangled many-body quantum state. However, if an observer…
Modulated symmetries from generalized Lieb-Schultz-Mattis anomalies
Hiromi Ebisu, Bo Han, Weiguang Cao
Symmetries rigidly delimit the landscape of quantum matter. Recently uncovered spatially modulated symmetries, whose actions vary with position, enable excitations with restricted…
Matrix product state classification of 1D multipole symmetry protected topological phases
Takuma Saito, Weiguang Cao, Bo Han +1
Spatially modulated symmetries are one of the new types of symmetries whose symmetry actions are position dependent. Yet exotic phases resulting from these spatially modulated symm…
Noninvertible operators in one, two, and three dimensions via gauging spatially modulated symmetry
Hiromi Ebisu, Bo Han
Spatially modulated symmetries have emerged since the discovery of fractons, which characterize unconventional topological phases with mobility-constrained quasiparticle excitation…
Exotic phase transitions in spin ladders with discrete symmetries that emulate spin-1/2 bosons in two dimensions
Bo Han, David F. Mross
We introduce a spin ladder with discrete symmetries designed to emulate a two-dimensional spin-1/2 boson system at half-filling. Using global properties, such as the structure of t…
